Definitions

  • the present utility model relates to a device for holding dental handpieces in the apparatus where they are disinfected and sterilized, especially apparatus applied to dental units.
  • One method of sterilizing dental equipment used preferably when the dental unit is not in operation, envisages an intermittent cycle (for example, see patent applications EP - 111.249 and EP -317.521, the latter being by the same Applicant as the present), during which the mains water supply to the handpieces is turned off and sterilizing liquid is fed into the handpiece pipes through a "dedicated" branch of the system equipped with an independent tank. After a defined time, which depends on the degree of sterilization required and on the amount of sterilizing liquid used, the water supply is turned on again and the polluted waste liquid is rinsed out through the handpieces themselves.
  • an intermittent cycle for example, see patent applications EP - 111.249 and EP -317.521, the latter being by the same Applicant as the present
  • the instruments To recover the liquid and avoid dripping during the feeding in or rinsing out of the sterilizing liquid, the instruments, before the sterilization procedure is started, are placed in a specially designed container where the sterilizing liquid, polluted by the materials removed from the handpieces, collects.
  • the containers used for this purpose are not made as part of the dental units but are designed to be attached to the dental units near the drainage section, usually at the top of a column of the dental unit where the cuspidor bowl and the rinsing tumbler support plate are located.
  • Containers of this kind consist of a tub closed at the top by a lid having in it a plurality of openings designed to accommodate the handpieces and instruments to be treated.
  • the tub is usually equipped with appropriate drains placed at the drainage holes of the cuspidor bowl (see also patent DE-36.11.327) or which are connected to the main suction device of the dental unit.
  • the tub lid has tubular projections extending into the container, each of which is coupled with a cap that closes the projection and that has a handpiece retaining web and drainage holes, when the projection is occupied by a handpiece: this provides a firm holder for the handpieces to be treated, that occupies a limited space and having small holes (made in the caps) for draining off the waste liquid which thus flows to the bottom of the tank and out through the main drain.
  • the container In the structural design of a dental unit of the latest generation, the container is integral with the upper surface having the holes for the handpieces and is incorporated into the structure of the dental unit itself.
  • a solution of this kind has obviously made it much more convenient to run sterilization cycles, it has made inconvenient all the solutions based on capped tubular projections, since the inside of the container is no longer easily accessible.
  • the Applicant has created a device designed to hold handpieces in the sterilization and disinfection apparatus, that is suitable for autoclaving and that can be quickly and easily fitted to and removed from the seats of the container forming part of the dental unit.
  • the device disclosed is designed to hold dental instruments or handpieces 1 equipped with a work head 2 and is applied to the apparatus used for disinfecting and sterilizing the said handpieces.
  • Such apparatus forms part of a dental unit including a main base 4 with an upper portion 5 equipped with a container 6 consisting of a tub 7 closed by a lid 8 having a plurality of holes 9 each of which can accommodate a handpiece 1 at rest so as to allow the draining off of the polluted liquids flowing out through the feed hose lc of the handpiece 1.
  • the tub 7 and the lid 8 are integral with the dental unit's upper portion 5 which also accommodates a plate 20, for supporting a rinsing tumbler 21, and a cuspidor bowl 22: in particular, the tub 7 is located inside the lower section 5i of the portion 5, whilst the lid 8 forms an integral part of the upper section 5s of the portion itself, where the plate 20 and the cuspidor bowl 22 are made.
  • tubular elements 10 From the outside of the container 6, tubular elements 10, closed at one end to form caps, can be inserted into, and removed from, the said holes 9 (see arrow F, Fig. 4).
  • Each tubular element 10 is made of a flexible material, suitable for autoclaving (for example, a heat-resistant elastomer) and is equipped with means 11 for positioning it and fastening it to the lid 8, the said means being located at the open end of the tubular element 10. As shown in Fig. 1, there may be as many tubular elements 10 as there are holes 9 in the lid 8.
  • the numeral 12 indicates means for retaining the handpiece 1, located inside the tubular element 10.
  • the retaining means 12 consist of a plurality of flexible flaps 16 made at the top end of the tubular element 10; the flaps 16 extend inwards towards the centre of the tubular element 10, leaving an opening at the centre which, when the element is not being used, is smaller in diameter than the diameter of the handpiece 1 held by the tubular element 10: in this way, the handpiece is held in a slightly raised position so that its work head 2 does not touch the bottom of the tubular element 10.
  • the said positioning and fastening means 11 consist of a circular crown 13 made at the open end of the tubular element 10 and having a diameter D1 greater than the diameter D2 of the holes 9 in such a way as to form a surface to support the tubular element 10 applied to it.
  • the tubular element 10 also has a plurality of through holes 15 made radially in its surface immediately below the said ring 14 in order to allow the polluted liquids flowing out of the handpiece 1 to be drained off.
  • the disclosure therefore provides a convenient holder for handpieces 1 that is easy to attach and remove from the container 6 which forms an integral part of the upper portion 5 of the dental unit. Hygiene is also guaranteed by the fact that the tubular elements 10 can be autoclaved whenever necessary, since they themselves come into contact with the polluted liquids flowing out of the handpiece and into the drain at the bottom of the container 6. Moreover, all this is possible without altering the ergonomic and structural configuration of the container 6.
